Abstract: A horizontal roof deck assembly has a ribbed steel roof deck sufficiently strong to withstand specified gravity, uplift, and shear loads. Rigid substrate boards are positioned adjacent one another above the deck, defining end and side joints. End joints are parallel to and above a corresponding upper rib of the roof deck and are secured to the upper rib by compression disk fasteners spaced along the end joint. The side joints can be tongue and groove joints. Additional fasteners attach the substrate boards to the roof deck along the side joints, for wind uplift resistance, and for thermal movement resistance.

Abstract: A roof transition assembly for a roof deck having a corrugated sheet and a rigid sheet wherein a base component is positioned at the perimeter of the roof deck and has two legs. The first leg secures the base component to the corrugated sheet, and the second leg extends from the first leg, generally parallel to a free edge of the roof deck. The second leg includes an anchoring surface. An upper component positioned at the perimeter of the roof deck has a connector portion and an anchor portion. The anchor portion is secured to the roof deck, and the connector portion extends from the anchor portion and overlays and is secured to the anchoring surface of the base component, thus anchoring the base component and upper component to the roof deck.

Abstract: A steel roof deck diaphragm to provide structural rigidity to a building wherein loads of varying intensity can cause movement of structural members, which tends to generate noise when two members rub or work against each other. Corrugated sheets of high tensile steel are supported from below and span the distance between purlins, the corrugated sheets having over-lapping side edges and end edges and upper and lower surfaces. Non-metallic strips of felt form spacers positioned between the over-lapping side edges and end edges to prevent generation of noise resulting from relative movement of the corrugated sheets.

Abstract: The roof system is formed of a corrugated sheet of material anchored to a roof beam, a mineral board anchored to the peaks of the corrugated sheet having a moisture barrier, at least one layer of insulating material interposed between the mineral board and the corrugated sheet, and standing seam metal roof panels anchored to the mineral board. A staggered anchoring system is provided which eliminates thermal shorts from the outside of the roof to the inside roof beams.

Abstract: A composite roof/roof deck assembly and method of installation wherein a roof covering of polymeric sheet material is adhered to an underlying gypsum board roof substrate with a water based polymeric adhesive. The gypsum board has a porous fibrous glass matte facing to enhance bonding between the water-based adhesive and the gypsum board.

Abstract: A method of building a roof wherein a horizontally disposed roof deck assembly is formed comprising: a sheet of corrugated steel material, preferably having a symmetrical rib pattern wherein the quantity of steel is equally distributed above and below a neutral axis; a sheet of insulation material; and a sheet of rigid substrate material mechanically fastened together by screws. The screws extend through the rigid substrate and through ridges on the upper side of the corrugated sheet material to restrain the ridges from above against lateral distortion under loading, thus forcing the corrugated sheet to maintain its shape and operate to capacities in excess of its expected or predictable flexural load capabilities. The roof deck assembly is secured to a supporting structure and suitable adhesive material, such as asphalt, is employed for securing a waterproof covering thereover.

Abstract: A soil excavating and utility pole securing sleeve is disclosed which will, when rotated around a standing utility pole, excavate an annulus of soil between the pole and the interior of the sleeve. The excavating sleeve defines an elongated hollow cylinder having teeth and inwardly bent excavating doors or flaps at one end which moves the soil between the utility pole and the sleeve out the door or flap and compacts the soil into the earth surrounding the sleeve. The sleeve is rotated into the ground around the utility pole for half its length, left there, and the evacuated annulus of soil then filled with a mixture of epoxy, resin, fungicide, and aggregate, allowed to cure and harden in order that the utility pole, the filling, and the sleeve become one single structure with a strength greater than that possessed by the original utility pole when new.

Abstract: A building roof, having an optimum strength to weight ratio, and method of constructing the roof wherein a horizontally disposed roof deck assembly particularly adapted to provide diaphragm shear strength and shear stiffness is formed comprising: a sheet (12) of steel corrugated material, a sheet (14) of optional insulation material, and a sheet (16) of rigid substrate material mechanically fastened together by screws (18). The sheet (12) of corrugated material is welded to purlins (20) by elongated welds (40) formed to resist rotation of the corrugated sheet (12) in a horizontal plane. The screws (18) extend through the rigid substrate (16) and through rigids (11) on the upper side of the corrugated sheet (12) to form a truss-like structure extending generally parallel to the purlins (20). Weld washers 30 having elongated slots (35) are used to secure high tensile strength symmetrically corrugated steel (12) having a thickness in a range of 0.0144 inch to 0.
